Augmented reality gaming (AR gaming) is the integration of game visual and audio content with the user’s environment in real time. Unlike virtual reality gaming, which often requires a separate room or confined area to create an immersive environment, augmented reality gaming uses the existing environment and creates a playing field within it. While virtual reality games require specialized VR headsets, only some augmented reality systems use them. AR games are typically played on devices like smartphones, tablets and portable gaming systems. Pokémon GO,  considered the breakthrough AR app for gaming, uses a smartphone’s camera, gyroscope, clock and GPS and to enable a location-based augmented reality environment. A map of the current environment displays on the screen and a rustle of grass indicates the presence of a Pokémon; a tap of the touchscreen brings up the capture display. In AR mode, the screen displays Pokémon in the user’s real-world environment.
